/* A guess-the-word game, where the word is generated by getting Hunspell
   to suggest a dictionary word that 'corrects' a word made up of
   randomly generated letters.

   Two things of note: Hunspell can produce no suggestions if the random
   word is too strange, which prompted me to add an 'e' to the random
   letters. Secondly, the suggested word need not be the same length as 
   the random word (which is of length NUM_LETTERS).

  Usage:
    > compile JumbleGame.java
    > run JumbleGame
    e.g.
      Shuffled word is: eivfufla
      1/5. Make a guess: flavfuie
      - Nope
      2/5. Make a guess: effliav
      - Nope
      3/5. Make a guess: affvuiel
      - Nope
      4/5. Make a guess: fivefula
      - Nope
      5/5. Make a guess: laffiuve
      - Nope
      - Game Over. The word was: effluvia
